Chemical modification of β-lactoglobulin by quinines / Hemijske modifikacije β-laktoglobulina hinonima
(Serbian Chemical Society, 2003)
The avarone/avarol quinone/hydroquinone couple, as well as their derivatives show considerable antitumor activity. In this work, covalent modifications of β-lactoglobulin, isolated from cow milk, by avarone, its model ...
Comparisons of formic acid oxidation at supported Pt catalyst and at low-index Pt single crystal electrodes in sulfuric acid solution / Poređenje oksidacije mravlje kiseline na PT katalizatoru na nosaču i na niskoindeksnim PT monokristalima u sumpornoj kiselini
(Serbian Chemical Society, 2003)
The oxidation of formic acid was studied at supported Pt catalyst (47.5 wt%. Pt) and a low-index single crystal electrodes in sulfuric acid. The supported Pt catalyst was characterized by the TEM and HRTEM techniques. The ...
A glucan from active dry baker’s yeast (Saccharomyces cerevisiae): A chemical and enzymatic investigation of the structure / Glukan iz suvog aktivnog pekarskog kvasca (Saccharomyces cerevisiae) - hemijsko i enzimsko izučavanje strukture
(Serbian Chemical Society, 2003)
The structure of a polysaccharide consisting of D-glucose isolated from the cell-wall of active dry baker’s yeast (Saccharomyces cerevisiae) was investigated by using methylation analysis, periodate oxidation, mass ...
The current efficiency during the cathodic period of reversing current in copper powder deposition and the overall current efficiency / Iskorišćenje struje za vreme katodnog perioda reversne struje pri taloženju bakarnog praha i ukupno iskorišćenje struje
(Serbian Chemical Society, 2003)
The current efficiency during the cathodic period of reversing current in copper powder deposition was determined by measuring the quantity of hydrogen evolved. The diagrams from which the instantaneous and average current ...
Comparative electrochemical study of some cobalt(III) and cobalt(II) complexes with azamacrocyles and β-diketonato ligands / Komparativno elektrohemijsko ispitivanje nekih kobalt(III)i kobalt(II) kompleksa sa azamakrocikličnim i β-diketonato ligandima
(Serbian Chemical Society, 2003)
The electrochemical properties of eight mixed-ligand cobalt(III) and co balt(II) complexes of the general formulas [CoIII(Rac)cyclam (ClO4)2 (1)–(4) and [Co2II(Rac)tpmc](ClO4)3 (5)–(8) were studied. The substances were ...
The critical apparent density for the free flow of copper powder / Kritična nasipna masa za tečenje praha bakra
(Serbian Chemical Society, 2003)
A method for the determination of the critical apparent density, which permits the free flow of electrodeposited copper powder is discussed. It was found that powders the apparent density of which were larger than 2.3 g/cm3 ...
The role of the concentration profile of titanium oxide on the electrochemical behavior of RuO2-TiO2 coatings obtained by the sol-gel procedure / Uloga koncentracionog profila titan-oksida u elektrohemijskom ponašanju RuO2-TiO2 prevlaka dobijenih sol-gel postupkom
(Belgrade : Serbian Chemical Society, 2003)
In order to understand the role of TiO2 in the deactivation mechanism of an active RuO2–TiO2 coating, an additional TiO2 layer was introduced in the support coating interphase of regular Ti//[RuO2–TiO2 anode in one case ...
Antimalarial, antimycobacterial and antiproliferative activity of phenyl substituted mixed tetraoxanes / Antimalarijska, antimikobakterijska i antiproliferativna aktivnost fenil-supstituisanih tetraoksana
(Serbian Chemical Society, 2003)
Mixed tetraoxanes of the 4"-phenyl-substituted cyclohexyl-spirotetraoxacyclohexyl- spirocholate series have been prepared and evaluated as possible antimalarials, antiproliferatives and antimycobacterials. The activity of ...
